This subproject deals with how and when people negotiate their rights and responsibilities with respect to knowledge in order to communicate what they know. In most interactions there is an asymmetry between interlocutors not only in what they know, but also in how they know what they know. We will be examining how these asymmetries are attended to by conversational participants, and how authorisation to speak about knowledge is distributed and managed in conversation. We will be examining how conversation turns are designed to reflect the stance a speaker takes with respect to what they know; how turn design reflects which kinds of knowledge are treated as publicly accessible, and which kinds are treated as private or ‘owned’. We will also be examining when and how disputes over knowledge arise and how they are resolved.
